This is exactly what needs to be done. If that doesn’t stop them, then start withholding funds from the State, starting with Fed funds that go to illegals for housing, food stamps, medicaid, etc. Defund the crap out of their illegal activities and illegals in general.

FoxNews: President Elect Trump Threatens All Lawless Mayor’s Of Sanctuary Cities With A $650 Billion Cuts!

More than 200 U.S. ‘sanctuary cities’ won’t turn over people to federal officers seeking to deport them nor share information about them, saying that would rend the social fabric and impede policing. Since Trump’s election last week, mayors including San Francisco’s Ed Lee, New York’s Bill de Blasio and Chicago’s Rahm Emanuel have vowed not to back down.

“This city and so many cities around the country will do all we can to protect our residents and to make sure that families are not torn apart,” de Blasio said Wednesday after meeting with Trump at Trump Tower.

Many cities have calculated that dwindling populations and labor shortages can be ameliorated by immigrants, undocumented or not. The mayors must calculate the point at which resistance harms the communities they’re fighting to protect. The evolving confrontation exposes states’ and cities’ vulnerability to losing some of the $650 billion in federal funds they receive for everything from police to sidewalks as they confront pension obligations and shrinking budgets.
